Mr. Boone if memory serves me correctly the M490 is just the HI FI package. It is not Bose. What year is your car? I believe Porsche started putting Bose systems in the Boxster in late 2002. Up to that point the best system you could get was teh Hi Fi. Some included a 4 speaker system and others were 6 speakers. The easiest way to tell is if the OEM harness is stil in the back. The harness is on the passenger side right behind the rollbar next to the clam shell.
Do you have a storage box back there? If so are there little cubbies directly behind the seats or are they grills. If they are grills then that means you have speakers back there.
Check it out and let us know.
What year is your car?
